Problème Launcher custom 1.6.4

[4Spartan8]

Bonjour à tous !

Aujourd'hui je créer ce sujet pour vous demander de l'aide.

Alors voilà, j'ai créé un Launcher pour mon serveur en 1.6.4 grâce au tutoriel de @jambonlatex, disponible : ICI .

Il faut savoir que j'ai créé plusieurs Launcher il y à pas mal de temps avec le même tutoriel en 1.6.4 et que je n'ai jamais eu de problème ..

Bref, en gros, le launcher télécharge bien tout, mais au final, une fois qu'on à cliqué sur Play, il ce ferme et rien ne ce passe :/


Apparemment il n'arrive pas à charger la classe FML Tweaker :

java.lang.ClassNotFoundException: cpw.mods.fml.common.launcher.FMLTweaker

Voici les logs que l'on peut retrouver à la fin du launcher, une fois que celui-ci c'es fermé :

Merci d'avance
